Thanks to Brian Kuhn (refer title of this post) for the following piece of code to to make a List contain unique items only.

On a side thought, would this chew up lot of cpu/memory? Feel free to post your comments.

public List removeDuplicates(List items) {
Set set = new LinkedHashSet();
set.addAll(items);
return new ArrayList(set);
}
